Be it known that I, NIELs ANTON CHRIS- yTENSEN, a subjectfof the King of Denmark,

residing at Milwaukee, in the county ofMilwaukee and State of Wisconsin,- have inventf ed certain new and` usefullmprovements in Hose-Couplings, of whichthe followingis a specification.

^My invention vrelates lto hose-couplings; and its 'object -is to `produce a simple, ef-

-valve positively and automatically opened and closed bythe actof coupling or uncoupling two similar hose-couplings.L

The advantages` in .constructionv of. my

new coupling will'be apparent from the'description hereinafter given, taken in` connection with the drawings.'

" In the accompanying.drawings,'Figure1 is a section of two of'my couplings coupled together, with the f passages consequently open;l Figs. 2 and 3, plan'and side elevation, respectively, of the valve-seat; Figs. land 5, bottom plan and side elevation, respectively,

of thev valve, 'the lower portionofthe stem ofthe valve being partially away in"fFig2 5 to expose its pin; and Fig. 6`, a

coupling-heads.

r Y plan of one ofthe Each coupling-head 1`l contains.,` a valveseat 2, which is provided, preferably, witha Y series of holes or passages V3 and which is held onto a gasket 4 ,interposed between it and an annular flange V5. The seathas two .headless screws orpins 6 andv '7, the former screwing, into thel bottom of the valve-seat,`withitsf projecting headv entering ahole 8 in the an-A nular flange., while the other pin screws into.y

- the head or top of the valve-seat, with its proj ecting head forming a stop for the valve, as

hereinafter explained. The pin 6 serves not c only `to prevent rotation of the valve-seat, but also to locate such seat in proper relative position in assembling the parts. 1

Flach valve comprises a bodyQ and a stem "'10, having-a projecting Vpin 11 and a longitudinal hole or socket Y12 to receive the pin of an i opposing valve, as clearly shown inV Fig.. f1.

Each valve is pressed to its seat by a spring 153, bearing at one l end .against a cap 14, screwing into the head 1, and at the other end against the valve itself, being held-'centrally thereof preferably by the boss 1,5. The valvebody has a series of ports or passages 16 corresponding in number tothe passages 3 in the valve-seat and adapted to register therewith valve-'body is cut awayv to form the-recessor notch 17', (see Fig. 4,) which accommodates -thehead ofpin 7.. V v

The coupling-heads are similarand, as

' to enter or pass through, in both the coupling f and' uncouplin'g operations, the correspondlng notchon the Uother head similar to the shown, while the space between the lugsaccommodates the-portion 20a of Atheflange. Before two heads. can be disengaged por.' uncoupled it is necessarythat they'bemoved to one cer/tain angle defined by the lugs 18, which register 'at such time with the' openings or notches 19 ,inwhich defined angle or position bothvalves in'the heads'are in lap'orclosed position. This insures also first astraight movement in the plane' Vof said valves;v so Ythat theyare absolutely closed before the coupling-heads can be disengaged, and then a transversemovement when one ofthe lugs 18 registers with the-notch 19 of the coperating head, Theangle or relative position ofl the heads in the'uncoupling operation is side-movement being permitted; i. The coupling operation isthereverse of that-just' described. C j

VVhenftwo` similar coupling-heads are brought together into engagementin'the manner above" described, the projecting 'pins 11 enter the holes in the opposite valve-stem, so that when the angular movements take place in making'the couplingthe valves 9 will be moved onaccount of such engagement of the pins 11. The angular movement of the valves isy determined by thel pins 7, fastened in the Vseats 2 and 10,.-sothat if one valvemoves ahead of the other itrwill come to a stop as soon as the notch inthe valve 9 engages with its pin. The other valve then has to move. Both'valves have now beenV positively and, in fact, automatically moved so that theirvports or passages 16 have registered withfthe passages 3 intheV valve-seats, thereby permitting the air or other fluid vunder pressure to traverse'bothkheads, as indicated by the arrows in Fig.1. 'When the heads are coupled, as shown, the pro j ecting gaskets seat on each other; Iny disengaging the coupling-heads the actionisreve'rsed, Withthe result that both valves are automatically and positively movedandleft in lap' osition, the ports beshown, Fig-6, eachof them has a pair of lugs 18. and 18a, the latter one of which is adapted ing closedj before Ithe ugs 'of -the heads areA notch'V 19'inthe lipporflangey 2()A of thehead always the same with accuracy, no play: or

permitted to be disengaged, thereby avoiding all waste of air. The coupling-heads are thus not only positively closed against escape of air, but sealed against entrance lof dust, dirt, sand, or other injurious foreign particles.

While for convenience I have described more or less precise forms and details of construction, it is evident that various changes may be made therein without, however, departing from the spirit of my invention, and consequently I desire it understood that my invention is not to be limited zto structural details, except Where -so `expressly required by the terms of some of the claims. Furthermore, I contemplate `usin my invention in connection with hose-coup ings for whatever particular purpose employed. In fact, I contemplate so using the `same wherever applicable.

claim- 1. In hose-couplings, the combination of a coupling-head having a lug and also a iiange which is provided with ,a notch in its edge, said notch being arranged to permit the lug of a similar coupling-head to pass through in the coupling and uncoupling operation.

3. In hose-couplings', the combination of heads each having a pair of lugs 18 and a notch 19 to receive one of the lugs of a similar head coupled thereto, said notch and said received lug corresponding accurately to make a single and definite angle between.
